Imidacloprid is a new insecticide from the family of the neonicotinoids, which interact with the insect nicotinic acetylcholine receptor. The effects of imidacloprid at a dose that does not affect sensory or motor functions are studied on non-associative learning abilities in the honeybee. The behavioral procedure is the habituation of the proboscis(More)
Behavioral modifications of astronauts over time spent in microgravity conditions was investigated according to an ethological approach based on video recordings during the Spacelab-1 mission. The method consisted of a description and a quantification of motor activity of a subject (movement and orientation) while performing working tasks. Each period of(More)
A dental examination could be perceived by small children as an "at-risk" situation. The behaviors observed in these children during a dental examination depend not only on the examination situation but also on other factors, such as the sex of the child or the sex of the accompanying parent. The ethological method provided a means for evaluating behavioral(More)
A method was proposed to locate the nearby cues used by an animal in the case of transverse orientation, where the animal keeps a constant angle with a spatial cue. By studying the value constancy of the angles formed by a moving animal and the direction of all spatial points (constancy being expressed through more or less strong variances), we set up a(More)
1. Intracellular recordings were made from the retinula units of the cricket Nemobius sylvestris. The half width of the angular sensitivity function was estimated at 4,4 degrees. This mean acceptance angle is slightly smaller than the interommatidial angle. In these conditions of light adapted state and for ommatidia of the central eye region, an(More)
